lBOD-UCING PHONOGRAPHIC RECORDS.

Specification of Letters Patent.

Patented Apr. 18, 1911.

A li a i n flied, May28, 190?, Serial Ka -875,234. Renewed January 6, 1911. Serial in 801,242.

zen of the United States, residing at Philadelphia, in the county of Philadelphia and State of-Pennsylvania, have invented'certain/new' and useful Improvements in Producing Phonographic Records, of w ich the a specification. My invention relates to animpr ovement in means for producing phonographic re'cords.

One-of the objects of the invention is, to produce a record without actual contact between the means actuated by the vibrating diaphragm and the material onwhich the record is produced.

A second of the objectsis' to produce a' recording device provided with means to adjust the same forthe purpose of enlarging or reducing the pndulating recording lines. I

The drawing illustrates in perspective view a recording. device embodying my invention. I p

" In this device, 10 is th'esound collector and 9 the vibrating diaphragm. The recording means are here illustrated as the I siphon 1 dipping,with one terminal into the liquid 6, the otherl terminalbeing in juxtaposition to the plate adapted to have recorded thereon the .record. The means to suspend the siphon 1 are-here illustrated as 1 consisting of the horizontal thread 5 secured to the uprights 4, 4. To this thread is secured the plate 3 and on this plate is the tube 2. One of the legs of the siphon is carried through this tube. The plate 3 is connected through the rod 8'with the vibrating disk 9.

The 0 eration of this device is as follows: The disli 7 is rotatedat the required speed through one of the speed-mechanisms usuallyemployed in the production of phonographic records. The siphon 1 is then placed into the tube 2. If it is desired that the -undulations should be of great amplitude,,then the whole length of one of the legs of the siphon shall be drawn through the ,tube, and if it .is desired that the undulations should be of lesser amplitude, then the -siphon should be drawn upward, so that only part of one leg shall protrude from the tube 2. To produce records, of which part of the lines'should be of large and part of the lines of small amplitude, it is only necessaryithat the person in charge should, durand will issue from the other leg. liquid may consist eithei of a dark liquid,

l ing the time. that the sound Waves are impinged on the vibrating diaphragm, raise or lower the siphon. The liquid 6 will, as is well undertsood, rise in one leg of the siphon This such asink, or may consist of an etching fluid, or an etching-resisting fluid. Such in,

broad outlines are themeans for producing records and the means for changing the amplitude of these records at the will of the operator, without necessitating the chang ing of the means to produce the air-Waves.

Having now described my invention,what

I claim as newand desire to secure by Let ters Patent is 1. In a phonographic recorder, a vibrating diaphragm, recording means, means for yieldingly suspending said recording means independently of thediaphragm, means to permit the position of the recording means to be varied relatively to the suspending means, whereby the amplitude of the undulations may bevaried, and means to connect said suspending means to the diaphragm.

2. In a phonogra-phic recorder, a vibrating diaphragm, a recorder proper associated therewith, means for yieldingly suspending the recorder proper independently of the vibrating diaphragm, means for transmitting the vibrations of said diaphragm to said recorder proper, and a mounting for' the recorder proper to permit the position of the recorder proper to be varied in relation to said suspending means, whereby to increase or decrease the amplitude of the recorded lines.

3. In a phonographic recorder,-a vibrat ing diaphragm, a recorder proper associated therewith, means for yieldingly suspending the recorder proper independently of the vibrating diaphragm, means for transmitting the vibrations of said diaphragm to said recorder proper, and a connection between the recorder' proper'and said suspending means, whereby the position of the recorder proper may be shifted relatively to said suspending means to increase or decrease the amplitude of the recorded lines.

4. In a phonographic recorder, a vibrating diaphragm, a recorder proper associated therewith, means for yieldlngly suspending the recorder proper independently of the vibrating diaphragm, means for transmit ting the vibrations of said diaphragm to 6.3m a phonographic recorder, a vibrat ing diaphragm, a siphon, a support for said siphon yieldingly mounted independently of the diaphragm, abonneotion between said support and said diaphragm, and means to permit the position of said siphon relatively to said suspending means to be changed, whereby to vary the amplitude of the re-' corded lines.

In testimony whereof I ailix my signa- 25 ture in presence of two witnesses.
